Jig for ladder welding of a ladder fire engine

摘要

The present invention relates to a ladder welding jig of a ladder fire truck, the frame (2) having a bearing (3) and a rotating shaft (4) coupled to each of the upper sides; Worktables (6) having both centers coupled to the rotating shaft (4) on the frame (2) and rotated about the center; An angle adjusting means (8) installed at an upper side of the frame (2) and a work table (6) corresponding thereto to adjust a rotation angle of the work table (6); Fixing means (14) fixedly installed on the worktable (6) to fix and support the two side portions (22) of the ladder (21) on the worktable (6); Fastening to the corresponding portions of the end portion and the side portion 22 of the fixing means 14, corresponding portions of the upper and side portions 22 of the U-shaped bracket 18, and corresponding portions of the working table 6 and the side portion 22, respectively. It was provided with a ladder welding jig of a ladder fire truck consisting of a known clamp 20 for supporting the worktable 6, the fixing means 14, the two side portions 22.;Therefore, the right angle between the worktable 6 and the side portion 22 by the support jaw 16 of the straight bracket 15, the c-shaped bracket 18, and the clamp 20, and between the two side portions 22; The parallelism of the two sides 22 is securely supported, and in this state, welding the bottom portion 23 of the ladder 21 between the two side portions 22, the parallelism between the two side portions 22 and the side portion 22 and the bottom portion 23 The squareness between the two is firmly maintained to solve the conventional problem that the completed expensive ladder is not expanded or folded properly when it is unfolded or folded.
